Abstract

Common techniques for processing cellular service uses a signal cellular tower, but these techniques are limited to the capacity of the single cellular tower. In contrast, a system employing an example embodiment of the invention increases ability to process cellular service by using an access point access network using resident wireless devices, referred to as a femtocell. A system supports communications of a resident and roaming device while employing the access point access network, based on database information, to support soft handoff between adjacent femtocells or from femtocell to cell tower and vice-versa. As a result, the system enables the resident and roaming devices to have seamless transitions between the cellular access network and the access point access network. Thus, the access point access network supplements cellular access networks and can provide cellular service regardless of the capacity of the cellular tower.

Claims

1. A communications network, comprising:

a cellular access network;

an access point access network at least in communication with the cellular access network to support soft handoff between the access point access network and the cellular access network and having a database configured with information identifying resident devices associated with the access point access network;

an identifier module configured to identify signals of the resident devices and roaming devices, where the roaming devices are not normally associated with the access point access network; and

a service module to access the database and assign characteristics of service to support communications of the resident and roaming devices while employing the access point access network based on the information in the database and to support soft handoff to enable the resident and roaming devices to have seamless transitions between the cellular access network and the access point access network.

2. The network of claim 1 wherein the access point access network is one or more femtocells.

3. The network of claim 1 wherein the service module is configured to collect performance monitoring statistics of roaming devices and to provide the statistics to a management element.

4. The network of claim 1 wherein the identifier module is configured to store a device ID for the roaming devices in the database for later configuration.

5. The network of claim 1 wherein the service module configures separate flow paths for the communications of the resident devices and roaming devices.

6. The network of claim 1 wherein the access point access network is configured to provide access to the roaming devices in exchange for a fee.

7. The network of claim 1 wherein the access point access network uses power and/or backhaul from existing resources.

8. The network of claim 1 wherein the access point access network is configured to enable a capacity of the cellular access network at low transmission power to increase battery life.

9. The network of claim 1 wherein a user allows the sharing of data flow in the access point access network.

10. A method for managing femtocell traffic comprising:

communicating with a cellular access network to support soft handoff between an access point access network and the cellular access network;

configuring a database with information identifying resident devices associated with the access point access network;

configuring an identifier module to identify signals of the resident devices and roaming devices not normally associated with the access point access network;

accessing the database and assigning characteristics of service to support communications of the resident and roaming devices;

employing the access point access network for service based on the information in the database; and

supporting soft handoff to enable the resident and roaming devices to have seamless transitions between the cellular access network and the access point access network.

11. The method of claim 10 wherein the access point access network is one or more femtocells.

12. The method of claim 10 further comprising:

collecting performance monitoring statistics of roaming devices; and

providing the statistics to a management element.

13. The method of claim 10 further comprising storing a device ID for the roaming devices in the database for later configuration.

14. The method of claim 10 further comprising separating flow paths for the communications of the resident devices and roaming devices.

15. The method of claim 10 further comprising accessing the roaming devices, using the access point access network, in exchange for a fee.

16. The method of claim 10 further comprising using power and/or backhaul from existing resources to power the access point access network.

17. The method of claim 10 further comprising enabling a capacity of the cellular access network for low transmission power to increase battery life.

18. The method of claim 10 wherein a user allows the sharing of data flow in the access point access network.

19. A method for providing a wireless user with access point service, comprising:

contracting with access point agents to support wireless service via an access point in an access point access network;

contracting with a third party for the wireless services;

providing consideration to the access point agents for wireless service to the third party via the access points; and
